How Is H. Pylori Implicated In The Etiology Of Cancer?, Chaya S. Lowy Jan 2022

How Is H. Pylori Implicated In The Etiology Of Cancer?, Chaya S. Lowy

The Science Journal of the Lander College of Arts and Sciences

Gastric cancer is a major public health concern due to the many deaths it is associated with. H. pylori is present in almost all gastric cancer patients; thus, it is fundamental to understand how H. pylori is implicated in the etiology of gastric cancer. The research in this paper is primarily based on studies acquired from Touro College Online Libraries. The bacteria have the means to survive the harsh environment of the stomach by creating a safe microenvironment and propelling themselves toward safer territory. If the bacteria attach to host cells, H. pylori injects cytotoxin-associated protein A (CagA) and vacuolating …

Biological Sciences Faculty Publications

Most plastid genome sequences are assembled from short-read whole-genome sequencing data, yet the impact that sequencing coverage and the choice of assembly software can have on the accuracy of the resulting assemblies is poorly understood. In this study, we test the impact of both factors on plastid genome assembly in the threatened and rare endemic shrub Calligonum bakuense. We aim to characterize the differences across plastid genome assemblies generated by different assembly software tools and levels of sequencing coverage and to determine if these differences are large enough to affect the phylogenetic position inferred for C. bakuense compared to congeners. …

Maternal Stress And Excessive Weight Gain In Infancy, Katelyn Fox, Maya Vadiveloo, Karen Mccurdy, Sara E. Benjamin-Neelon, Truls Østbye, Alison Tovar

Nutrition Faculty Publications

Rapid weight gain in infancy increases the risk of developing obesity early in life and contributes significantly to racial and ethnic disparities in childhood obesity. While maternal perceived stress is associated with childhood obesity, little is known about the impact it has on infant weight gain. Therefore, this study explores the impact of maternal perceived stress on change in weight-for-length (WFL) z-scores and the risk of rapid weight gain in infancy. We conducted a secondary data analysis of the longitudinal Nurture birth cohort (n = 666). Most mothers in the cohort were non-Hispanic/Latinx Black (71.6%). About one-half of mothers had …

Effect Of Nest Box Temperature Mitigation Treatments On Nest Success And Nestling Condition In A Southeastern Population Of Eastern Bluebirds (Sialia Sialis), Christopher G. Horacek, Katie Stumpf, Wayne Powell

Graduate Research Showcase

Understanding behavioral responses of wildlife to climate change will be important as global temperatures continue to rise. Effects of rising temperatures may impact many species, including those that breed in seemingly protected nests, such as cavity nesting birds. Variations in nest cavity microclimate during the early development of secondary cavity nesting passerines may affect the growth of offspring and impact nesting success and survival. We examined the effect of two heat mitigation treatments (white exterior, n=11, and an internal foil heat shield, n=16) and nest box opening orientation (north, south, east, west) on internal nest box temperatures and the effect …

Should India Lend To Gdh The Same Weight As To Gdp?, Sudhavna Char Jan 2022

Should India Lend To Gdh The Same Weight As To Gdp?, Sudhavna Char

International Review of Business and Economics

Growth for growth's sake goes against the grain of sustainable economics. It is not maintainable on the basis of full-cost pricing. The billing should include health and environmental costs, including charges for the exhaustion of natural resources, egregious disparities in wealth distribution, and increases in mental and physical sickness. Today’s material growth model transmutes many economic endeavors into preying on current and future generations. Unwittingly, the single-minded pursuit of growth without a global perspective has been resulting in loss of life and property, besides undermining prospects of life’s basics for upcoming generations. This is myopic, ignoring catastrophes hitting home. In …

Repurposing Of Small Molecule Inhibitor Ym-155 Inhibits High-Risk Neuroblastoma Growth By Directly Inhibiting Survivin Protein, Danielle Crystal Rouse Jan 2022

Repurposing Of Small Molecule Inhibitor Ym-155 Inhibits High-Risk Neuroblastoma Growth By Directly Inhibiting Survivin Protein, Danielle Crystal Rouse

Theses and Dissertations

High-risk neuroblastoma (NB) is an aggressive pediatric tumor which develops from the extracranial sympathetic nervous system and accounts for almost 15% of all childhood cancer-related deaths. Current therapies include high-dose chemotherapy and radiation which have long-term toxic side-effects. Despite these intensive therapies, the overall survival rate of NB is less than 50%. Therefore, developing novel therapeutic approaches by directly targeting the molecular mechanisms that drives NB progression is very important. In the present study, we analyzed genomic datasets of 1235 NB patients and discovered that overexpression of survivin coding gene BIRC5 strongly correlates with poor overall and event-free survival of …

Human Otop1 Proton Channel Can Function As A Monomer, Gabriella Abigail Ulloa Jan 2022

Human Otop1 Proton Channel Can Function As A Monomer, Gabriella Abigail Ulloa

Theses and Dissertations

Otopetrins (OTOP) represent a new family of eukaryotic proton channels that do not share structural similarities with other renowned ion channels. Otop1 was initially known for its involvement in vestibular function and its significance for otoconia formation before it was established as a bona fide sour taste receptor. The cryo-EM structures for several Otop channels have been determined and demonstrated Otop1 as a homodimer comprised of two subunits. Each subunit constitutes twelve transmembrane helices that can be further partitioned into two structurally similar six transmembrane domains designated as the N and C domains. Molecular dynamic simulations have also previously shown …

Prior Adaptive Semi-Supervised Learning With Application To Ehr Phenotyping, Yichi Zhang, Molei Liu, Matey Neykov, Tianxi Cai

Computer Science and Statistics Faculty Publications

Electronic Health Record (EHR) data, a rich source for biomedical research, have been successfully used to gain novel insight into a wide range of diseases. Despite its potential, EHR is currently underutilized for discovery research due to its major limitation in the lack of precise phenotype information. To overcome such difficulties, recent efforts have been devoted to developing supervised algorithms to accurately predict phenotypes based on relatively small training datasets with gold-standard labels extracted via chart review. However, supervised methods typically require a sizable training set to yield generalizable algorithms, especially when the number of candidate features, p, is …

Retinal Detachment: What Are The Types And Potential Causes?, Mera Skoblo Jan 2022

Retinal Detachment: What Are The Types And Potential Causes?, Mera Skoblo

The Science Journal of the Lander College of Arts and Sciences

Retinal detachment is one of the few ocular emergencies. Depending on the extensiveness of the detachment, and whether it is macula on or macula off, will affect the patient’s visual acuity after treatment. Therefore, it is vital that after experiencing any common retinal detachment symptoms, the patient sees an ophthalmologist immediately. High-risk factors for retinal detachment include aging, ocular trauma, high myopia, and prior eye surgery. Statistically, the cause of a given retinal detachment often determines the specific type of detachment that occurs. There are three forms of retinal detachment, categorized separately based on their anatomical characteristics.
